4.1.3 Digital Output
4.1.4 RS-232
R3000 supports digital output with wet
contact. Please refer to the right side figure
to connect the negative pole of the power
to the port marked “GND”.
The maximum output voltage, output
current and output power of DO is 30V DC,
0.3 A and 0.3 W respectively. It means that
the voltage difference between Out1, Out2
and GND cannot exceed to 30V DC; and the
current value through Out1 and Out2
cannot exceed to 300 mA; while the output
power dissipated by Out1 and Out2 cannot
exceed to 0.3W. Otherwise, the DO will be
damaged.
R3000 supports one RS-232 for serial data
communication. Please refer to the
connection diagram at the right side.
